Me (pointing enthusiastically): "Dude, check it out, there's a wishing well in the front yard of that house!"
Sippy Cup (unimpressed): "Yeah. I saw it the other day when I came home from school."
Me: "Do you know what you can do with a wishing well?"
Sippy Cup: "Yeah. You take a coin, drop it in the well and then you make a wish."
Me: "What would you wish for?"
Sippy Cup (stopping to think): "A star."
Me: "You'd wish for a star? Why?"
Sippy Cup: "A shooting star. So that I could make more wishes whenever I wanted."
Me (sighing): "Oh. Of course."
